Mary McCarthy (not to be confused with another screenwriter—Mary Eunice McCarthy) was an American screenwriter active in the 1930s and 1940s.
[1] Born and raised in San Francisco, California, to Irish parents (just like the similarly named screenwriter), McCarthy pursued a career as a schoolteacher in San Mateo, California, before giving it all up to run a nonprofit sandwich stand.
She then became a political activist, stumping the state for the Democratic Party and going toe-to-toe with the Ku Klux Klan.
[1] Eventually she headed to Hollywood to pursue a career as a scenarist in the mid-1930s; her first big credit was on Theodora Goes Wild, a 1936 comedy starring Irene Dunne.
